FPC AllKey: The Next Generation of Fingerprint Simplicity

Our most advanced fingerprint system yet, compact, powerful, and ready for standalone or connected  biometric deployments.

Introduction

Meet FPC AllKey — our latest, most integrated biometric system-in-package (SiP). Built for speed, security, and simplicity, AllKey brings biometric performance to any product with minimal effort.

Whether you’re building smart locks, authentication tokens, safes, or secure access systems, FPC AllKey delivers a complete biometric experience in one compact module — with no need for external software or biometric knowledge.

Available in two variants:

  • FPC AllKey – streamlined, high-performance biometric system

  • FPC AllKey Pro – enhanced security features, secure host interface, and extended template management

And with support for mesh deployments, FPC AllKey enables synchronized fingerprint access across multiple devices, allowing you to build powerful, connected experiences in homes, hotels, and enterprises.
